As the information society appears, the increasing power and access of personal computers along with wide spread use of the information technology has not only changed the landscape for communication but it has opened up new and exciting opportunities for education. One of the ways that information technology could help improve education is to be used in interactive communication to share the knowledge and experience of all the teachers as well as students. In this paper, the use and application of information communication technology[ICT] into mathematics classroom are described and showed several examples. furthermore, the web site design and developed for this study was introduced of the purpose of sharing the ideas about the knowledge and usage of the history of mathematics and examples of mathematical connections. The study suggests that enabling mathematics in incorporating of ICT by teachers and students requires more effort to be made in training teachers on the use and application of ICT into mathematics classroom.

The computation cost of image registration is affected by searching data size and space. This paper proposes an efficient image registration algorithm that uses multi-resolution wavelet decomposed image to reduce the data size search. The algorithm determines the correlation detection at low resolution on low-pass sub bands of wavelet and generate mask for higher resolution as part of a coarse to fine registration algorithm. The correlation matching is defined for coarse resolution similarity measurement, while mutual information (MI) is used at fine resolution. The results show that the new efficient mask-based algorithm improves computational efficiency and yields robust and consistent image registration results.

In recent years, future information and communication technology (ICT) has influenced and changed our lives. Without various ICT-based applications, we would have difficulty in securely storing, efficiently processing, and conveniently communicating information. In the future, ICT will play a very important role in the convergence of computing, communication, and all other computational sciences and application. ICT will also influence various fields including communication, science, engineering, industry, business, law, politics, culture, and medicine. In this paper, we investigate the latest algorithms, processes, and services in future fields.

This article investigates the topology control problem in the space information network (SIN) using a hierarchical autonomous system (AS) approach. We propose an AS network topology control (AS-TC) algorithm to minimize the time delay in the SIN. Compared with most existing approaches for SIN where either the purely centralized or the purely distributed control method is adopted, the proposed algorithm is a hybrid control method. In order to reduce the cost of control, the control message exchange is constrained among neighboring sub-AS networks. We prove that the proposed algorithm achieve logical k-connectivity on the condition that the original physical topology is k-connectivity. Simulation results validate the theoretic analysis and effectiveness of the AS-TC algorithm.

This paper presents the performance analysis of a long-range marine communication system developed for monitoring the fishing gears. LoRa based buoys were developed to monitor fishing gears. The buoy sends its coordinates along with other relevant information to the central monitoring station via a gateway. During the experiment, a up to 30 km of communication between a buoy and a gateway was successfully tested.

In this study, the information and communication technology ICT companies, 312 companies, in order to analyze the impact of the effect of satisfaction on the Exhibition and Convention on the impact of Information and Communication Technology Exhibition and Convention satisfaction effects analysis by information and communication technology Convention e-Portal affect the infrastructure system, exhibition and Convention, Convention Industry competitiveness, Convention, Convention Tour Program components to satisfy Convention effect empirically the effect on information and Communications Technology exhibition and Convention industry Convention and satisfaction effects on were analyzed. A result was able to find that information and communication technology goods and technology, tourism technology infrastructure technologies program, e-portal system, industrial competitiveness and technology Exhibition and Convention of Effects. Exhibition and Convention ensure the effect of the base material and environmental factors, these factors determine the product development laid the foundation. Product type defined, you can see that affecting economic ripple effects and satisfaction. Exhibition and Convention can achieve the effect of information and communication technologies to reduce your operating costs.

Objectives: To validate the role of a new information and communication technology platform that we created for the betterment of the oral health of persons with disabilities and for providing appropriate health care services. Methods: A Delphi survey was conducted among 16 people in various professions, including academia, government agencies, and dentistry, to evaluate the validity of the information and communication technology platform. Moreover, platform satisfaction was evaluated using a user experience questionnaire among 200 people, including persons with disabilities, parents, and public institutions. Results: Experts in consensus indicated a high validity for the categories of service provider (CV=0.29, CVR=0.69), service target (CV=0.29, CVR=0.38), service contests (CV=0.27, CVR=0.63), and financial support (CV=0.30, CVR=0.63) in our information and communication technology platform. In addition, information from questionnaires on user experience and communication technology satisfaction analysis showed that both users and providers were highly satisfied with the platform. Conclusions: The provision of oral health services based on the new information and communication technology platform has numerous advantages, in addition to providing adequate oral health care for the disabled. Furthermore, the social safety net for improved oral health may be further strengthened.

This paper proposes a design and implementation of transversal adaptive digital filter using LMS (Least Mean Squares) adaptive algorithm. The filter structure is based on Distributed Arithmetic (DA) which is able to calculate the inner product by shifting and accumulating of partial products and storing in look-up table, also the desired adaptive digital filter will be multiplierless filter. In addition, the hardware implementation uses VHDL (Very high speed integrated circuit Hardware Description Language) and synthesis using FLEX10K Altera FPGA (Field Programmable Gate Array) as target technology and uses Leonardo Spectrum and MAX+plusII program for overall development. The results of this design are shown that the speed performance and used area of FPGA. The experimental results are presented to demonstrate the feasibility of the desired adaptive digital filter.
